"men’s greater tendency toward systemizing and mechanistic thinking means that they often try to “figure out” their relationships with their girlfriends as if they are logical systems or a carburetor. They don’t realize that relationships involve other human beings with emotions and feelings, which are not always rational and logical, and they instead treat other people as if they were machines. Similarly, women often talk to their cars and copy machines, as if they had minds and feelings. They don’t realize that they cannot really relate to their cars and copy machines, because they have no feelings or emotions; they have no “minds” they can read."

So true! I've been adjusting the A/F ratio, swapping jets, etc on my girlfriend and still haven't been able to get her running right
